Curious, I asked them what it was and I was intrigued enough to try it out.

So the way it works is: I eat three meals within an eight-hour period and then fast for 16 hours. I have my first meal at 12 p.m., a snack at 4 p.m., and dinner at 8 p.m. It is important to note that I don't snack in between my meals. Why?

Let's briefly discuss the difference between the fed state and the fasting state.

The fed state is when your body is digesting food, which lasts for three to five hours from when you begin eating.

During this time it is hard for your body to burn fat because your insulin levels are high.

Once the fed state is done, your body enters the post-absorptive state, which lasts for eight to 12 hours after your last meal.

This is when you start fasting because it is easier for your body to burn fat when insulin levels are low.
